Question

About 1,500,000 bacteria are found in 1 milliliter of water of coastal ocean. How many bacteria will be there in 100 milliliters of water?
A. 1.5 × 104
B. 1.5 × 105
C. 1.5 × 106
D. 1.5 × 107
E. 1.5 × 108

Answer 1

Answer: E.  $1.5\times10^8$

Explanation:

Given: The number of bacteria found in  1 milliliter of water of coastal ocean. =$1,500,000$

Then, the number of bacteria found in  100 milliliters of water of coastal ocean =$1,500,000\times100$

⇒ The number of bacteria found in  100 milliliters of water of coastal ocean =$150,000,000$

In standard notation, $150,000,000=1.5\times10^8$

Hence, the number of bacteria found in  100 milliliters of water of coastal ocean = $1.5\times10^8$

Answer 2

The correct answer for this is E. 1.5 x 10^8 because it wants you to convert the answer into scientific notation so if the answer is 150000000  then the answer would be what i said above
